What are the Causes of Schamberg Disease? (Etiology)

  • The exact cause of Schamberg Disease is not well-established or understood. But a dysfunctional immune system may be a causative factor
  • The skin discoloration occurs due to the inflammation of capillaries with leakage of red blood cells into the surrounding tissue. As the RBCs breakdown, the iron in the hemoglobin get deposited in the skin causing its discoloration
  • The condition is not infectious and does not spread from one individual to another

What are the Signs and Symptoms of Schamberg Disease?

The clinical signs and symptoms of Schamberg Disease include the following:

  • Localized (confined to a certain area), well-circumscribed areas of patches on the skin in the form of papules and macules, which are many in number
  • The skin patches are occasionally itchy, but are usually not painful
  • The onset of the patches takes place slowly, beginning from the lower legs. It then spreads to the rest of the body

How is Schamberg Disease Diagnosed?

The diagnosis of Schamberg Disease may involve the following procedures:

  • The diagnosis is usually made by a good physical examination and evaluation of medical history
  • Dermoscopy: Dermoscopy is a diagnostic tool where a dermatologist examines the skin using a special magnified lens
  • Complete blood count (CBC) and other blood tests to rule out any infection
  • Skin biopsy: A skin biopsy is performed and sent to a laboratory for a pathological examination, who examines the biopsy under a microscope. After putting together clinical findings, special studies on tissues (if needed) and with microscope findings, the pathologist arrives at a definitive diagnosis. A skin biopsy is performed to rule out other similar conditions

Many clinical conditions may have similar signs and symptoms. Your healthcare provider may perform additional tests to rule out other clinical conditions to arrive at a definitive diagnosis.

  • Development of worsening and recurrent chronic skin lesions, which may be resistant to treatment
  • The longstanding skin patches can cause emotional stress and psychological trauma in some individuals, leading to depression

  • The presence of chronic skin lesions may cause psychological discomfort; individuals may require reassurance to help with stress and anxiety

Despite therapy, the skin lesions persist for a long period of time, resulting in a chronic skin disorder.

There is currently no effective means of prevention of Schamberg Disease, because the cause of this condition is unknown.
